Summary: This system has no optical, digital coax, or even composite audio (RCA jack) inputs. It only works with HDMI Audio Return Channel (ARC), which is only available on newer HD TVs. Be sure to check for this capability on your TV before buying. My LG TV supports ARC but still would not work with this speaker system because of incompatible implementations of the HDMI 1.4 standard by LG and Sharp.
Summary: Do not buy this unless your tv has an arc enabled hdmi. No controls on unit at all so need to interface through tv and if you don't have ARC it won't work unless the3.5mm input jack is used. This resulted in poor quality and uncontrollable sound with my samsung.
Summary: I bought the Sharp HT-SL50 thinking that it could be suitable for My samsung LED TV. The Item itself seems very nice, very pretty item, no doubt about it, it suited perfectly my TV. I did not need an expensive sound system, just something that coul improve the weak speakers of my TV. But sadly, you have to be aware that it won't work with all TVs.
